Application filed September 2, 1909.v Serial No. 515,818.

To all whom it may concern:

Be it known that I, Josarn E. Annina cltlzen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lamps, of2 which the followmis a specification.

y invention relates to lamps and more specifically to that class thereof designed for use upon an automobile.

The object of my invention is the pro vision of a lamp of the character mentioned which will be efficient, strong, and durable, and which will be extremely simple 'of construction, hence of low cost to manufacture:

a further object being to provide a lampwhich, because of its simplicity, may be readily cleaned and repaired.

Other objects will appear hereinafter.

With these objects in view my invention consists generally in a lamp characterized as above mentioned, the body of which may be formed of a single piece of glass effectually reinforced'at different places by encirmetallic rings.

y invention further consists in certainV details of construction and arrangement of parts all as will be hereinafter fully described and particularly pointed out in the ap ended claims.

y invention will be more readily un'- derstood by reference to the accompan drawings forming a part of this specification, and in which,

Figure 1 is a central vertical section of my lamp in its preferred form, Fig. 2 is a transverse section taken on line o o of Fig. 1', 3 is a. transverse section taken on line y-g of Fig. 1, Fig. 4 is a sectional detall illustrating the detachable connection between the remforcin and the lam-p bod Fig. 5 is a side e evation of a slightly m edformofm device, .isacentral section thereofY taken on e z z of Fig. 5, and Fig. 7 is a section taken on line wiiwf ofFig' 6' I h die 11 e now to t e y eFigTL-goml aiinch'sweis shown the referred form of my lamp, 1 designates the body of the lamp which, as clearly illustrated, is formed of a single piece of glass, the lenses or bulls eyes 2, which are provided upon three sides of the body, being formed integral with the latter. The top 3 of the body 1 is open, the same being provided with a perforated metallic cap 4, the same being sec thereon by engagement with a bead 5 formed upon the former, the perforations provided in said cap se in the capacity of draft openings. The ottom. 6 of the body is also open, the same as shown, being dared preferably semi-spherically formed to snugly recelve a suitable oil burner 7. Provided at opposite sides of the reservoir 8 of the latter, the upper extremities thereof being suitably secured close to the upper of the lateral surface of the former, are resilient arms 9 the lower end portions of which are bent Ato engage a circumferential inwardly extending flange or bead 10 provided close to the lower edge of the body portion 6.

outwardly exten flanges 11 and 12 provided at the upper and lowerextremities respecvely of the reservoir 8 engage the inner surface of the body portion 6 and the latter thereof also the under side of the flange 19, when said locking arms 9 are in locking engagement with the latter, theY same thereby limiting upward movement of the burner in the body 1 and facilitating a rigid connection between said burner and body. A s shown, the arms 9 are so formed that by simply inserting the burner 7 sufficient-ly far into the lower end of the-body, the saineY will, by their own resiliency, rock ontw .in into locking engagement with the 10, as Ibefore stated.

In order toY effect ready and' expeditious attachmentv of the burner from the body,

circumferential arms 9 are formed to depend through slots 13A provided in theperiphery of the inlge 12 for the reception thereofto substan v y the lower extremity of the burner or to such au extent as to be readily accessiblethrough the lower op ww of the-body 1. With such provision detachment of the burner may be e'ectedby simply suciently inwardly rocking the lower ends ofthe arms 9, such rocki thereof being evidently readily effected y means of the fingers.

In order to accommodate the wick operating stein 14C of the burner in the insertion or removal of the latter, a slot 15 of cor-' responding shape, as clearlyshown in F' 3, is formed in the body 1 for the ceptibix thereof. nPerforations 16 provided in each of the flanges 11 and 12 serve in of draft openings.

Encircling the body 1 at substantially the center thereof, preferably just above and the capacity just belov;r the lenses 2, are two reinforcing detachable or adjustable Wire rings 17, e former being, as shown, prelerably provided with two circumferential grooves 18 for the reception of said rings. ln order to permit of the adjustment of said rings upon said body or of the removal thereof thereoru, one .ol the ends of each of the former is provided with an eye 19 adapted to receive the opposite end thereof, a nut- 2ll threaded upon the lastnamed end of each, adapted to engage the eye 19 thereof, being evidently adapted to eeet the adjustment desired.

Having the upper and lower end portions of its base plate 21 resting beneath the rings 17, the latter acting as a securing means therefor to the body 1, said ends being prelerably formed so as to be snugly received in the grooves 18, asshovvn in Fig. 1, is a suitable bracket 22 whereby the lamp may be attached to a suitable support. To prevent lateral movement of the brachet 22 upon the body 1, the outer surface of the latter is preferably formed at the place olf connection of said bracket thereto, with longitudinally extending beads or ribs 23 so spaced and positioned that the longitudinal edges of the plate 21, when the latter is properly arranged upon said body, Twill rest in engagement therewith, such provision evidentlyV fulfilling the desired purpose.

In Figs. from 5 to 7 inclusive l have shown a slightly modibed :form of my dcvice, the lamp therein shown being especially designed to serve in the capacity of an automobile head light, Whereas thatalready described as my preferred form,

designed to serve as an automobile tail light. In the modied form, 1 indicates the body of the lamp which is substantially cylindrical in form, open at its uper end, as in my preferred form, the same being provided yvith a perforated metallic cap d serving in the same capacity as the cap d and se cured to the lamp body in the same manner as the latter. Reiniorcing metallic rings 17 encircling the body 1 are also provided, the same being seated in circumferential grooves 1S formed in the outer surface of said bodyfsaid rings being secured in eractly the same manner as the rings 17 provided in my preferred iorm. The supporting bracket 22 oi this form is substantially the same in construction as the braclret the lateral edges of the base portion 21 thereof being secured under the rings 17 in the same manner as the upper and lon/'er edges oi the corresponding portion ol the bracket. 22. the outer surface oi the bodv 1 prevents vertical movement oi the brablret 2li' upon y the latter. Thus far, it will be observed, the two forms of lamps are substantially Beads or ribs 23 formed upon andere of the diderent purposes for which thel same are designed, dil'erentiate in a few minor details, which will be brought out in the following, and are found to be expedient. ln view of the lamp being used as a head light a gas burner 7 of suit-able design is incorporated instead of the oil burner 7.

2st indicatedraft openings provided in the bottom of the body. However, such openings need not necessaril be incorporated since openings adapte to serve in the same capacity might, if desired, be provided in the closure traversing the open front side of the body. A suitable relector 25 is provided rearwardV of the burner 7', the saine being removably held in a. position resting against the rearward Wall of the body, by a split spring ring 26. The front side of the body 1, as stated, is open, the month edge thereof being preferably slightly dared and formed with a bead 27 embracing which is a metallic protecting edging 28. Secured by a hinge 29 to the edging 28 is an annular metalhc lens holder 30 in which is mounted a suitable lens 31. A spring hooked arm 32 secured to and for- Wardly projecting from the edging 28 is adapted to engage the outer e ge ot the holder 30 to lock the same in closing posi tion.

ln either form of my lamp the outer surtace of the glass body thereof will be sand blasted or ground to Aform the same translucent, the lenses alone being left clear and transparent.

With the provision of a lamp of the construction shown and described, one of neat appearance, eiiectual in use, one which may be readily cleaned, and one Which is stron durable and economical in construction Wi l be provided. The metallic trimmings of the glass body 1, it will be observed, are so attached to the latter, that in the event of the body being broken, the former may be removed therefrom and readily arranged upon a .new body.

`While l have shown what l deem to be the preferable forms of my construction, l do not Wish to be limited thereto, as there might be various changes iliade in the details o construction and the arrangement of parts without departing from the spirit of the invention comprehended Within the scope of thc appended claims. And al- 1 though l have designed my lamp with special reierence to its usc upon automobiles l' may incorporate my ideas in lamps of any other design to which they are applicable.
